Labels and tooltips¶

Labels and tooltips can come from the row behind each point, for every chart type:

New-UDEChart -Data $vms -Type tree -Path Folder -LabelTemplate '{Name} ({Cpu} vCPU)' `
    -TooltipColumns 'vCPU=Cpu', 'Memory (GB)=RamGB:integer', 'Disk=DiskBytes:bytes', 'PowerState'
New-UDEChart -Data $links -Type graph -Source From -Target To `
    -TooltipTemplate "{From} > {To}`nVLAN: {Vlan}`nLoad: {Load:percent100:0}"

A placeholder {Column} or {Column:format} takes any format; a list column is joined with commas; `n starts a new line. -LabelColumn Name is the short form of -LabelTemplate '{Name}'. -TooltipColumns entries are Column, Column:format or Label=Column:format. Points without a row of their own (a tree's folders, aggregated nodes) keep their name. Values are HTML-escaped in tooltips.

-DataLabels writes the values on bars, lines and points; -LabelFormat formats them.

Legend¶

-Legend Bottom | Top | Left | Right | None places the legend; -LegendType Scroll (default) pages through entries that do not fit, Plain wraps them over several lines.

Labels on filled shapes¶

Labels inside a filled shape (funnel stages, pie slices with inside labels, treemap tiles, sunburst rings) are dark or white, whichever contrasts more with the fill; a label.color in -Options wins.

A funnel stage too small for its label (the last stages, or every stage of a low chart with many of them) gets the label on one line right of the funnel, with a line to the stage, in the page's text colour; the funnel gets narrower for it. Where even that leaves too little room, the label is hidden; the tooltip and the legend name the stage.
